2.1 WHAT IS INTEROPERABILITY AND WHY IS IT IMPORTANT?
The full realization of Joint Vision 20101 and the revolution in military affairs, discussed in Chapter 1, is predicated on a concept of information superiority enabled and supported by a network of C4I systems--one whose constituent elements interoperate and cooperate to support the entire warfighting hierarchy, in the context of joint and coalition operations. Interoperability of C4I systems is a key enabler of the overarching operational goal of force integration--the fusing of the services and coalition partners into a unified military force that achieves high military effectiveness, exploiting and coordinating the individual force capabilities. Achievement of a high level of interoperability requires a commensurate level of effort and resource prioritization throughout DOD. Today, DOD is just at the beginning of refining and even establishing the processes and organizations to respond to future needs for C4I interoperability.
